SPECIFICATION forming part of Letters Patent No. 664,601, dated December25, 1900.

Application filed August 27, 1900. Serial No. 28,196. (No model.)

To all whom, it may concern:

Be it known that I, JOSEPH H. ANDERSON, of the city of St. Louis, Stateof Missouri, have invented certain new and useful Improvements in Hand-Cultivators, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart hereof.

This invention relates to hand-cultivators and it consists of the novelconstruction, combination, and arrangement of parts hereinafter shown,described, and claimed.

Figure 1 is a side elevation of my improved hand-cultivator. Fig. 2 is aplan view from above. Fig. 3 is a view corresponding to Fig. 2 lookingfrom below. Fig. 4 is a front view of an attachment by means of whichthe plowpoints are attached to the handle. Fig. 5 is a view showing theattachment having a pronounced concavity in the under side Whereby thearms carrying the plow-points may be adjusted at various angles. Fig. 6is a detail View showing a modified form of the attachment.

In the construction of my improved handcultivator I provide a handle 1,secured to the lower end of which is a ferrule 2, integral. with whichis a plate 3. The said plate 3 is preferably formed with a concavedunder surface and is provided on its forward edge with a dependingflange 4., formed in which at suitable intervals are notches 5.

6 indicates the outer arms or plow-beams, formed on the lower ends ofwhich are the plow-points 7. The arms 6 are integral with the secondarms 8, forming a continuous U- shaped rod, and on the lower ends of thearms 8 are formed the plow-points 9, which, as shown, are a suitabledistance in advance of the plow-points 7. The arms 6 and 8 rest withinthe notches 5, and a bolt 10 passes between the said arms and throughanopening in the plate 3 and carries on its upper end a nut 11, wherebythe said bolt may be tightened and the arms 6 and 8 be retained firmlyin position. The concaved under surface of the plate 3 causes the arms 6and 8 to be gripped very firmly whenever the nut 11 is tightened,drawing the head of the bolt closely against the under side of the saidarms. This concavity also allows the arms to be adjusted at variousangles relative to the handle, which results in much greater convenienceto the user. The construction of arms on both ends of the plate 3 isidentical. By having the arms formed in series and integral with eachother a single plate may be used to attach the arms to the handle, and asinglebolt is all that is required to attach each pair of arms to theplate.

Carried within the two central notches 5 are the shorter arms 12, whichare integral with each other and are provided on their lower ends withthe plow-points 13, which are even with each other and are a suitabledistance in advance of the plow-points 7 and 9. A central bolt 14 passesbetween the arms 12, thereby forming a means by which the said arms 12may be rigidly retained in position.

In Fig. 6 is shown a modified form of plate by means of which theplow-points may be attached to the handle and comprises the ferrule 15at a suitable angle with a plate 16, having a smooth undersurface andprovided on its forward edge with a depending flange 17, having aplurality of notches corresponding to the notches 5. The plow-points areattached to the plate 16 by means of bolts corresponding to the bolts 10and 14.

A hand-cultivator constructed as described forms a very convenient toolfor the cultivation of garden-plants. The plow-points may be securelyattached to the plate and may be removed therefrom in case of injury andoth- 85 ers. secured to the plate instead. The device is light andsimple and possesses superior advantages over those of ordinaryconstruction.

It may be stated in this connection that the elevations 4 are wider thanthe diameter of 0 the bolt, and promising this fact it will be adjustedat difierent angles relative to the rality of arms havingplow-pointsbn-sthein lower ends carried by the said plate, thesaidarmsubeing withinthesaid notches, substantially as specified,

3. A hand-cultivator, consisting of a handle,'a--platev1 having anintegral depending flange and notches formed in said flange, carried bythe said handle, a series of 'pairs of arms, the arms of each pair beingintegral with each other, and resting in the said notch-es, -a singlefastening device for each pair :of arms, plow-points formed on the saidarms, and means for adjusting the said plowpoints atndifferentelevations relative to the said plate, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
